(CNN) - Minnesota's Supreme Court has dismissed former Sen. Norm Coleman's challenge to the state's November election results and declared Democratic challenger Al Franken the winner.
The unanimous opinion ruled that Franken "received the highest number of votes legally cast" and is entitled "to receive the certificate of election as United States senator from the state of Minnesota."
The former "Saturday Night Live" writer and performer had declared victory in the disputed race after a recount ended in January, but Coleman - a Republican who had been seeking a second six-year term - went to court to challenge those results.
Coleman still could attempt to take the challenge to federal courts, but Minnesota Gov. Tim Pawlenty, a Republican, told CNN on Sunday that he would sign Franken's election certificate if the Supreme Court ordered it.
